TMG – The First 64-bit Microsoft Firewall


Yesterday I was talking with Richard Hicks and he was telling me how excited he was with the new set of features that TMG has.  This is indeed true, many people got really excited with the package of new features that TMG Beta 2 brought, but there is something that you might not realize it yet. TMG is design to run in a Windows Server 2008 64-bit platform…ok, and what this means? Well, this means robustness to your edge device. This means the capability of scale your environment to other levels while your edge device is not the bottleneck of the traffic. To summarize the technical values of what this really means, check it out this table:

If you think about it is very interesting to see this in another perspective, because for a firewall standpoint it is not every day that you see such high numbers.
